I hunt with a muzzle loader in Washington State during the Muzzle loading elk season. I am allowed to have fiber optic sights, two green dots and one center red dot. Since I have prisms in my eyeglasses due to double vision, I see three green dots, then three red dots and three green dots when I sight my gun. What is the solution to this prism and bifocal problem and open sights?
